WHAT IS SO-DIMM DDR2?

WHAT IS SO-DIMM DDR2?

DDR2 SO-DIMM memory modules commonly have clock speeds from 200 MHz upward (specifications). 204-pin SO-DIMMs can also contain DDR3 SDRAM, with specifications such as PC3-6400, PC3-8500, PC3-10600, PC3-14900 and PC3-17000. Some SO-DIMMs provide ECC functionality; unbuffered ECC SO-DIMMs are called SO-CDIMMs.

WHAT IS SO-DIMM slot?

In notebooks , Small outline Dual Input Memory Module (SO-DIMM) slots are used since there is lack of space in smaller and compact devices. SO-DIMM slots takes half the space in comparison to DIMM slots, but they draw higher power than its bigger variant.

Are there different types of DDR2 RAM?

Double data rate 2 SDRAM (DDR2 SDRAM) is the successor to DDR SDRAM. Other common speeds for DDR2 SDRAM modules include PC2-3200 (DDR2-400; 3200Mbps throughput); PC2-5300 (DDR2-667); PC2-6400 (DDR2-800); and PC2-8500 (DDR2-1066).

Is Sodimm backwards compatible?

1 Answer. No. PC2700 is DDR (Double Data Rate), whereas PC100 is not.

How many pins is SODIMM?

SO DIMM sockets are designed for the latest DDR4, as well as previous versions DDR3, DDR2, DDR, and SDRAM memory modules. For DDR1 and DDR2 SO DIMM sockets, the pin count is 200 pins; for DDR3 SO DIMM sockets, the pin count is 204 pins; for DDR4 SO DIMM sockets, the pin count is 260 pins.

When was DDR2 phased out?

Double Data Rate 2 Synchronous Dynamic Random-Access Memory (DDR2 SDRAM) is a double data rate (DDR) synchronous dynamic random-access memory (SDRAM) interface. It superseded the original DDR SDRAM specification, and was itself superseded by DDR3 SDRAM (launched in 2007).

WHAT IS SO DIMM designed for?

A SODIMM (Small Outline Dual In-line Memory Module) is a memory module with a smaller outline and thickness than standard DIMM modules and designed primarily for notebook computers.

Is my RAM SO DIMM?

To determine whether the modules are DIMM or SODIMM, use these steps: Open Start. Type Command Prompt, right-click the top result and select the Run as administrator option. Otherwise, if the command output the number 12, the computer uses SODIMM modules (typically available on laptops).

Is DDR2 DDR compatible?

DDR2 DIMMs are not backward compatible with DDR DIMMs. The notch on DDR2 DIMMs is in a different position from DDR DIMMs, and the pin density is higher than DDR DIMMs in desktops. DDR2 is a 240-pin module, DDR is a 184-pin module.

Is DDR2 compatible with DDR4?

DDR2 won’t fit into a DDR4 slot. No. All DDR generations are different, in their operating frequencies, voltages as well as in the physical slot. DDR2 won’t fit into a DDR4 slot.

What is the difference between DDR2 and DDR2 SO-DIMM?

This variance is designed to prevent coupling of memory and controllers of different DDR generations due to electrical incompatibility. DDR SO-DIMMs operate at 2.5 V while DDR2 SO-DIMMs operate at 1.8 V. These modules, while using the same physical layout, may differ in the specified voltage – 1.5 or 1.35 volts.

What is the difference between a DIMM and a SO-DIMM?

SO-DIMMs are nearly equal in power and voltage rating to DIMMs; SO-DIMM technology does not mean lower performance compared to larger DIMMs. For example, DDR3 SO-DIMMs provide clock speeds such as 533 MHz (1066 MT/s, PC3-8500 ), CAS latencies such as 7, and higher capacities such as 4 GB per module.

Is the 200-pin SO-DIMM compatible with DDR3?

The 200-pin SO-DIMM can be of the types DDR and DDR2. In both cases the notch is located at one fifth of the board length (20 pins + notch + 80 pins), but in DDR3 the notch is located slightly closer to the center of the board. These two types of memory are not interchangeable.

What is a 204-pin PC3-10600 DDR3 SO-DIMM?

A 204-pin PC3-10600 DDR3 SO-DIMM A comparison between 200-pin DDR and DDR2 SDRAM SO-DIMMs, and a 204-pin DDR3 SO-DIMM module A SO-DIMM slot on a computer motherboard A SO-DIMM, SODIMM, or small outline dual in-line memory module, is a type of computer memory built using integrated circuits.
